In previous tutorials, you've made maps from layers created by other people. That's great up to a point, but eventually, you want to make maps from data that you've found, compiled, or created yourself. One way to do this is with an editable layer. Editable layers let you draw shapes directly on a web map and define pop-up windows for these features.
In this tutorial, you'll make a points of interest map for Redlands, California. You can tailor this kind of map to various purposes: to show points of interest in your own city, to document trips or explorations, or to map locations on a subject of interest to you: surf spots, ghost towns, airport cafes, or whatever it might be.
There should be just one search result: a map called Redlands Places.
The map opens to a view of Redlands, California.
The map has just one layer: the Topographic basemap. There's not much to this map, apart from its list of bookmarks.
The map zooms to a hilltop flanked by orange groves and trees. The Kimberly Crest House, a local landmark, is the building circled in the image below.
Features of interest, such as buildings, streets, parks, and lakes, may be labeled on some basemaps and not others. If you're trying to identify a place, it may help to change basemaps. It so happens that none of the ArcGIS Online basemaps label the Kimberly Crest House as of this writing.
You'll mark the Kimberly Crest House as a point of interest.
The side panel becomes the Add Features panel and shows symbols for drawing features on the map. On the ribbon, the Edit button is selected. This means that you're in Edit mode and can add, delete, or move features.
A template, in this context, is a palette of map symbols. The Map Notes template has generic symbols; other templates have more specific uses.
A stickpin is added to the map and a pop-up window opens.
We can do a lot more with pop-up windows. We'll come back to this in a moment.
In the Contents panel, the layer you created appears above the basemap layer.
The map is added to your My Content page.
Now you'll reopen the pop-up window for the Kimberly Crest House and add links to an online image and a website. You can link to images hosted on any public website, such as social media and photo-sharing sites.
The feature is selected and its pop-up window opens.
This Panoramio page has pictures by Esri employee Piotr Andzel.
You need to copy the image location—that is, the image's URL—not the image itself. In Mozilla Firefox (v. 13), the command is Copy Image Location. In Google Chrome (v. 19), it's Copy Image URL. In Microsoft Internet Explorer (v. 8), click Properties on the context menu, then highlight and copy the address (URL) on the Properties dialog box.
When a map user clicks the stickpin symbol, the pop-up window will show a thumbnail version of the image. Clicking the thumbnail will open the website.
The side panel disappears. It will come back if you click the Details button or the Edit button.
Issues of copyright protection and fair use with respect to image links may need consideration on your part. (Image links point to an image on a host computer while displaying, typically, a small, low-resolution version of the image on a client computer.) In this case, the photographer has given permission to link to the images.
You should make sure the pop-up window looks and works the way you want it to.
You should see a thumbnail version of the image (showing a view of the gardens from the house).
Images with a landscape orientation fit the image space better than those with a portrait orientation.
The Kimberly Crest website should open in a new browser tab or window.
You might want to use a symbol other than the green stickpin.
The pop-up window becomes editable.
The basic symbols include stickpins, pushpins, flags, and other icons.
The new symbol appears on the map.
The Points of Interest layer will eventually include diverse features like buildings, parks, and streets. You can use a single symbol to represent all these features or a different symbol for each feature type (one symbol for buildings, another for parks, and so on).
Click the Edit button to toggle the map in and out of Edit mode.
The map zooms to the site circled in the image below. Like Kimberly Crest, the Morey Mansion isn't labeled on the basemap (as of this writing).
Add some more features on your own. All the bookmarked locations in the map have corresponding photos on the Panoramio site. (Note that the photos span two pages.)
Most of the remaining sites are labeled on the Topographic basemap, but a few (the Olive Avenue Market, the Asistencia Mission, and the Santa Fe Depot) are not. Try using other basemaps, especially OpenStreetMap, to pinpoint these locations. Or Google the sites for address information that you can enter in the Find Address or place box.
As for websites, you can link to the examples below or to web resources you discover yourself.
Olive Avenue Market
Santa Fe Depot
You may also want to mash up your editable layer with existing map services for Redlands. Use the keyword "Redlands" to search ArcGIS Online for layers that might enhance your map.
You can use all sorts of shapes to create features in an editable layer. You can mark buildings with a point symbol, such as a Stickpin; draw routes with a line symbol, such as Line or Freehand Line; and use area symbols, such as Area, Rectangle, or Circle, to show neighborhoods or other areas of interest that aren't defined on your basemap.
